Abstract
A control apparatus for a fuel injector has a microcomputer which calculates a basic pulse width of pulses to be applied to a fuel injector. When the voltage of a battery which powers a fuel pump and the fuel temperature fall below levels which cause the discharge pressure of the fuel pump to drop below a prescribed pressure, the microcomputer corrects the basic pulse width by lengthening it to compensate for the drop in fuel pressure. Pulses having the corrected pulse width are applied to the fuel injector.
